We have enabled Change Data Capture for auditing our table changes in SQL Server 2008. There is a request to NULL out a few columns (for all rows) in a couple CDC tables, due to compliance with a certification. Is there a compelling reason not to modify these tables and to leave the audit trail as-is?
View 1 RepliesAgain, looking for the best way to do this with SSIS.
I have a source table and I'd like to load it to a database daily, capturing what changed.
This is not a dimentional table but a fact table.
So, what I;d need to do for each record is to see if the record already exists (using business key) and if it does - compare some of the data fields and of there are changes - register it somehow and if not changes ignore.
Right now, the only two ways I see to do it with SSIS:
- Use Slowly Chaging Dimentions transformation
- Use Lookup and customize SQL, adding something like: WHERE key = ? and (field1 <> ? or field2 <> ?...)
I was wondering of there an easy way.

When using Change Data Capture on SQL Server 2012 I have researched that you cannot truncate data in a table. Is this also true if one wanted to delete data from the table? Getting a little confused about what DDL statements can be ran against a table with CDC enabled. Does CDC have to be disabled before performing certain DDL statements against a table?
I would like to safeguard the truncation and dropping of certain tables within the dbo schema. Wondering if I could do this with one fail swoop with CDC enabled on those tables. The other option would be to use a DDL trigger to prevent certain DDL statements to be performed.
Is there a built in functionality to do the CDS in SSIS 2005? if not, what is the best way to do this in ssis 2005?
View 2 Replies View RelatedI have a requirement to implement CDC for 50+ tables to implement incremental data changes warehouse/reporting rather than exporting the whole table data. The largest table is having more than half a billion records.
The warehouse use a daily copy of OLTP db (daily DB refresh). How can I accomplish this. Is there a downside in implementing CDC just for the sake of taking incremental changes on the tables?
Is there any performance impact if we enable CDC on OLTP db?
Can we make use of the CDC tables on the environment we do daily db refresh so that the queries don't hit OLTP database?
What is the best way to implement CDC to take incremental changes for reporting.
I am using SQL Server 2012 and to me a part of data captured by CDC is not making sense.
I have a table called 'Schema.Table1', and I enabled CDC on it by running 'sys.sp_cdc_enable_table'. I see that a table called 'cdc.Schema_Table1_CT' got created which now gets an entry when ever I Insert, Update or delete a record in the original table.
Till this point every thing works fine.
My original Table has a NOT NULL INT column called 'AuditTrackerUserID' with a default value of 1996. My application does not provides a value for this column, but because the column itself has a default value, records get inserted without error.
When I try to execute the following Query I see multiple records with __$operation of 3 and 1.
SELECT * from cdc.Schema_Table1_CT where AuditTrackerUserID IS NULL
My expectation is that I should not ever see any record returned by this query because AuditTrackerUserID is a not null column, but I do.

Hi All,
I am now working on the design phase of my project, we are looking to implement Change Data Capture (CDC) but i need some help if you guys has implemented before using the SSIS 2005 componets. I am trying to use the Following:
Source---------Derived Column---------Lookup---------------Conditional Split (to split New records and Updated Records)-----------Destination. Respectively.
Lets make it clear, my source holds (Old records and newly added or Updated records), the Derived Column is to Derive new columns called Insert_Date and Update_Date. The Lookup i am Using is to look the Fact_Table(the Old Records) as Reference, and then based on this lookup i will split the records on timely based using the Conditional Split. My question is
1. Am i using the right components?
2. what consideration should i have to see to make it true (some Logics on the conditional split)?
3. Any script which helps in this strategy?
4. If you have a better idea please try to help me, i need you help badly.
Thank you,
SamiDC
I have 5 tables that are joined respectively,
Each one of the tables listed below has a “CreateDateTime” and “UpdateDateTime” fields, I need to get yesterday changes, I can get any record where either CreateDateTime or UpdateDateTime is greater than midnight yesterday butI need to watch dates on all of the tables so I need to do atleast 10 date checks.
If any table shows an updated or created record, I need to gather ALL of the information for that customer. So, if my name didn’t change (SCUS table), but my email does (SEML table), I have to pull out both the SCUS and SEML tables (and the others, of course). So It may not be simple WHERE clause, How can I achieve this:
SELECT
SCUS.CUSFULLNAME
,
SCUS.CUSMIDDLENM
,
SCUS.CUSLASTNM ,
[Code] ....
Or can it record before and after column changes based on the LSN only?
An extract from a file based legacy accounting system is performed every night. The system does not have a primary key because transactions are managed through program code. (the more things change...). The extract is copied to text in Unix and FTP'd to Windows, where the file is loaded into SQL Server by kill & fill. Because of the expense of modifying the source system, there is enormous inertia/resistance to injecting a primary key at the source, so kill & fill it stays.
In reading about Change Data Capture, it seemed to me that column level insert update and delete are stored in tables that remember the before and after content of each column tracked. In my reading I have seen many references to the LSN to decide when and what to record as changed, but I have not seen any refereference to the necessity of a primary key for Change Data Capture to work. This is in contrast to replication, where the requirement for the existence of a primary key is made plain.
Is it possible to use Change Data Capture against a table without a primary key? How to use it to change the extract from kill and fill to incremental.
I have located a bug in the functions cdc.fn_cdc_get_net_changes_<capture_instance> generated when you enable cdc on a table. This bug can be triggered if 2 rows are created in the _CT table having the same values for the __$start_lsn, __$seqval and the table's key column(s). From research on the internet I have found such rows can be created by a "deferred update": a single update statement in which a column that is part of a unique constraint is updated.
In order to report the bug with Microsoft I need to create a complete series of steps-to-reproduce. But even though the situation happens several times a day in our production environment, I have not yet been able to reproduce it in my test environment.I need a single update statement (plus maybe some steps in advance) that make that the log reader inserts 2 rows into the _CT table, one with __$operation = 1 (delete) and another with __$operation = 2 (insert) as opposed to the single row with __$operation = 4 that it inserts for a normal update. Below is the script I have so far to create a fresh database, enable cdc, create a test table, insert some data and update this data.
I would have liked the last update statement to be handled as a "deferred update". However in all of my tests the log reader just simply inserts a single row into the cdc.dbo_NETTEST_CT table.how to reproduce the situation where I get the 2 rows with __$operation 1 and 2 from a single update statement instead of the single row with __$operation = 4.

Hi.
I have tables (they are empty and there are no constraints) with columns typed as varchar. In a database I want to change the type of all the varchar columns in all the tables from varchar to nvarchar. What's the best way to do it? Can you suggest code?
I know that to get all the relevant columns I would issue a query like this
select *

where data_type = 'varchar'
Then I would use a cursor... And that's exactly what I would not like to do. Is there any other way?
Thanx.

HiI tried posting this query in microsoft.public.sqlserver.programming but gotno response.I am new to replication but I am trying to setup up a transactionalreplication of tables from one database to another in MSSQL 2000 (SP2).My target tables have primary keys defined. Under publication properties Igo to the snapshot tab and for each table I clear the check box that says"Drop the existing table and re-create-it" and "clustered Indexes." On thispage the nothing is checked. for each table.Whenever the subscription is reinitialized it drops the primary keys on mytarget tablesand replaces them with a unique clustered index on the column that used tobethe Primary key.Is this normal? Is there anyway to stop it from doing this?I don't plan to send the snapshot more than once and let transactionalreplication take over for keeping my source and target in sync, but if Iever have to reinitialize the subscription, it would seem that I (orsomeone) willhave to take the a second step of manually dropping these clustered indexesand recreating the primary keys on the target table.Thanks in advance.---Dick Christoph---Dick ChristophJoin Bytes!612-724-9282

I'm not the most knowledgable DBA, I've had to learn almost completely on my own, AND on a production server, because it's the only MS SQL Server I have access to.
Everything was fine before I took down the production server for maintenance. Someone suggested that I re-index my tables because I was having some performance issues with a particularly large table (it didn't help that table btw), so I did re-index.
Now, Everything works wonderfully, except for the performance issue mentioned AND one other thing that is going horribly wrong.
Here is the table:
create table ABMcontactlink
(
classifier varchar(20) not null, /* Classification of contact. */
transmitter varchar(36) not null,
contact integer not null, /* Link to ABMcontact (detail) table */
primary key (classifier,transmitter,contact),
foreign key (contact) references ABMcontacts(identifier),
group_name varchar(20) null,
priority smallint null, /* Authorization level. */
type smallint null, /* Autoalarm or Manual */
last_modification_date datetime, /* Date/time record last touched */
last_modification_id varchar(40) /* Who last touched record */
)
go
create index IndexABMcontactlink on
ABMcontactlink(classifier,transmitter)
go
create index CandidateABMcontactlink on
ABMcontactlink(transmitter)
go
As you can see, I have the primary key, which creates a clustered index, PK_ABMContactlink_Some Number, and two other indexes.
Now, this is a very busy production database, and most quick short queries benefit more from CandidateABMContactlink than from the other two indexes.
Unfortunately, in this production system, and this table, seconds count ALOT, so when I have roughly 3000-4000 quereies an hour pulling information from this table, I personally beleive I need to keep CandidateABMContactlink, and I'm not willing to find out on a production server.
** Now to the Problem at Hand **
I have one query that kicks off about 7 times a day, used to take less than 1 minute before the re-index. NOW it takes 30 Minutes. And it drags the system to a crawl.
I did some looking into it, and this query is using CandidateABMContactlink, and it takes 30 minutes. If it uses PK_Abmcontactlink it finishes in under 45 seconds.
Most queries are simple, "Select Column_names from abmcontacts where identifier in (select contact from abmcontactlink where transmitter = 'XXXXXX')"
This one is:
select * from ABMcontacts where (
(last_modification_date >= '2006-04-28 04:40:03' and last_modification_date <= '2006-05-09 16:41:14')
and EXISTS(select contact from ABMcontactlink where contact = identifier
and EXISTS(select transmitter_id from ABMtransmitter where transmitter_id = transmitter and (dealer = 'XXXX'))))
or
(EXISTS(select contact from ABMcontactlink where
(last_modification_date >= '2006-04-28 04:40:03' and last_modification_date <= '2006-05-09 16:41:14')
and contact = identifier and EXISTS(select transmitter_id from ABMtransmitter where transmitter_id = transmitter and (dealer = 'XXXX'))))
I can't change the query, so how do I make it use the Index I want it to use without removing the index that it is using? (I know there are much better ways to write the above query, I'm not the culprit, if I could re-write it, I would)
I'm in the process of converting a rather huge VSAM database into a set of SQL tables.
I am using the same data names from the mainframe (like XDB-NAME to RDB-NAME).
I load the files using Import Export Data and it makes the tables with such column names as col001, col002, col003, etc... and always sets the data types to varchr(255).
And I have to cut and paste the data names from the manframe side to the server side (and the data types to.)
So, is there an easier way to do this? Or am I doomed to cut-n-paste my days away...
Thanks for any help.

Hi,
I was asking how can I make updating and deleting for data through database views in Microsoft SQL Server 2005
Best Regards,
I have a project where I need the ability to update data in a SQL table (SQL 2008) from a tool like Access or Excel. My SQL table has 3 records: Employee number, Employee Name, and a yes / no value (1 or 0). I want to be able to display the table data (in Access or Excel), and be able to have the user modify the yes / no value, but not the Employee number or Employee name. How to handle this in SQL. Should I connect Access directly to the SQL table?

View 1 Replies View RelatedHi all,
Having some fun with an excel import.
I have a excel sheet that has data that needs to be UpSert'ed into 2
different tables. In addition, I need to use a value in the spreadsheet
to determine the PK from a reference data table, for one of the UpSert
oprations.
That is all working now.
The thing I'm struggling with is something I am sure is quite simple -
but I'm not seeing a solution from attempts, googling or BOL.
2 of the columns I receive have either nothing, or X in them. The columns they go into are defined as BIT, NOT NULL.
So, in SQL it would be something relatively simple like:
CASE
When IsAvailable = 'X' then 1
When IsAvailable is null then 1
ELSE 0
end
But I don't know how to do this to data that was in a spreadsheet, and
now is a resultset being handed from a task to another task.
to outline my current solution:
---- table 1 = this all works -------------
Excel Source --> MultiCast (For Table 1)-->Data conversion for
table1-->:Sort for Table1--> Merge Join for table 1 (left Outer
join) as 'left' leg
Table1 Source --> Sort Table1 --> Merge Join for table 1 (left Outer join) as 'right' leg
Merge Join for table 1 --> Conditional Lplit for table1
Conditional Split for table1 (table1 source PK is null) -->Insert Into Table1 Destination
Conditional Split for table1 (table1 source PK is not null) -->Update Table1 OLE DB Command
---- table 2 = this needs to be able to convert X/NULL to BIT -------------
MultiCast (For Table 2)-->Copy Column for Table2 -->Data
Conversion for Table 2-->table3 lookup to get FK-->Sort for
Table2 merge-->Merge Join for table 2 (left outer join) as 'left' leg
Table2 Source --> Sort Table2 --> Merge Join for table 2 (left outer join) as 'right' leg
Merge Join for table 2 --> Conditional split for table 2
Conditional split for table 2(table2 source PK in null) -->insert into table 2
Conditional split for table 2(table2 source PK in not null) -->update table 2 ole db command
-----------------------------------------
Now, if I correct the spreadsheet to have 0's and 1's in the two
column, then the process above works. But I cannot (yet) force business
to do that.
If tried to use SQL Command for the excel source, but there is limited
functionality on the command - I cannot do SQL coalese, isnull or case
statements, which would allow me to resolve that data at source.
I've tried to use derived columns to alter the columns. I think that
the REPLACE (IsAvailable, VariableContainingX,VariableContaining1)
might work to change X's to 1, but that doesn't resolve the NULL issue.
I've tried to use a script component to handle the conversion - which
REALLY feels like a bad way to do this - the .Net script is wrote was:
-------------.net script code-------------

Any ideas?
In my SSIS package, I have a data flow task
I am loading a CSV file into a SQL table (OLE DB destination)
I have a couple of CSV files to be loaded
Instead of creating a separate task for each file , can I combine them together into a single task
I was thinking about using a ForEach container
This approach works if the number of columns in all the CSV files is same
But in my case it is not
So what I want is a script task that dynamically modifies the mappings
Can I do this?
I was browsing the net and I found certain code which uses IDTSExternalMetadataColumn90, MapOutputColumn etc.
But the code was creating a new package for each mapping
I couldn't understand the code
So can you please help me with this?
My script task should modify the mappings in my data flow task
For e.g.
If I have 3 columns in my CSV and 3 columns in DB, they should be mapped in the same order
P.S. I do not want to use configurations
Please help figure out what is wrong with my code. The script is supposed to load a package (from file). The loaded package already has everything set up to run a query against a local server and output the results to an Excel file. The reason for the outer script is because I need to change the query based on a global variable. When the query changes, though, I think the existing dataflow Path is no longer valid, so I should remove it and re-create another one with the new input mappings. Here is my code, which runs and throws an exception at the AcquireConnections call.
The error is
Error: 0x2 at Script Task: The script threw an exception: Exception from HRESULT: 0xC020801B

Hi all,
I have several reports using single shared datasource. I want to change at a runtime database that is used by that datasource. Can this be achieved? If not what are the other solutions I guess that using not shared datasource for each report may be the solution (is it?) but it is not the best solution for me. My goal is to allow users to run the same set of reports, viewed in ReportViewer control, but using different databases (connection string dependant).
Thanks in advance for any suggestions
Hi there,
Completely new to the world of databases. I'm a designer who works primarily in Flash. In any case, I'm trying to manage an application that uses MS SQL and learn about the wonderful world of databases.
Ok, I modified a table (e.g. I added a column called "Rate") that had associated views (created by another developer). Noticed that my application went a little wonky as some of my variables within my app took on the value of the data in the "Rate" column. I checked one of the views and noticed that a column within the view (e.g. TutorID) was assuming the values in the "Rate" column. Note: The column TutorID had been blank before the change to the table. I'm completely lost as to why this is happening. Do I need to rebuild the view? Can I just reset the original view?
Thanks.
Oh yeah, I'm using SQL4X Manager J from Mac Guru (if that helps).
If data is modified (by an insert, update, or delete) while the backup is running, will the backup contain those changes or will it be added to the database afterwards?
